底面为菱形的直棱柱\(ABCD-{{A}_{1}}{{B}_{1}}{{C}_{1}}{{D}_{1}}\)中，\(E\)，\(F\)分别为棱\({A}_{1}{B}_{1},{A}_{1}{D}_{1} \)的中点．

\((\)Ⅰ\()\)在图中作一个平面\(\alpha \)，使得\(BD\subset \alpha \)，且平面\(AEF/\!/\alpha .(\)不必给出证明过程，只要求作出\(\alpha \)与直棱柱\(ABCD-{{A}_{1}}{{B}_{1}}{{C}_{1}}{{D}_{1}}\)的截面\()\)．

\((\)Ⅱ\()\)若\(AB=A{{A}_{1}}=2,\angle BAD={{60}^{0}}\)，求点\(C\)到所作截面\(\alpha \)的距离．
